Abstract
The invention discloses a kind of Water filtration structure, including screen pipe, water inlet pipe is provided with the lower end shaft core position of the screen pipe, upper end cover and bottom end cover are internally provided with the screen pipe, the bottom of the upper end cover is provided with core, and PP cottons are combined between the upper end cover and the bottom end cover.The preparation technology of the PP cottons of Water filtration structure is optimized the present invention, modified diatomite is with the addition of in raw material, the PP cottons prepared carry out that PP cotton products are made after acid etch processing, and PP cotton products prepared by the present invention have good fracture strength, bacteriostasis property and heavy metal ion adsorbed performance.
Description
Technical field
The present invention relates to a kind of Water filtration structure.
Background technology
Common Household water tap does not have a filter effect, and the filter effect of traditional anion filtering tap compared with
Difference, it is impossible to effectively get rid of the particulate matter and harmful substance in water.As industry is developed rapidly, in factory's three wastes and sanitary sewage
Contained substantial amounts of toxic organicses and heavy metal ion, seriously pollute poisonous and harmfulization in drinking water source, water body
Pollutant load is learned year by year to rise.The conventional water treatment process of drinking water can not efficiently go dissolubility in water removal poisonous and harmful
Material, needs badly develop a kind of new Water filtration structure at present.Polypropylene has a good chemical stability, acid and alkali-resistance, resistance to
High temperature, corrosion-resistant and cheap, biologic packing material, microporous barrier for being made using polypropylene as raw material etc. have been widely used for
In water treatment field.Polypropylene superfine fiber melt-blown filter is a kind of novel microporous filter medium that developed recently gets up.It by
The hot melt entanglement of superfine polypropylene fiber is made, and superfine fibre is by itself bonding and tangles, and forms space random mixed and disorderly three-dimensional micro-
Pore structure, and radial fiber changes in gradient, is the synthesis of porous type and textile type filter medium, can with filtering accuracy
Lean on, the rate of filtration is high, pollutant carrying capacity big, length filter cycle, easy backwash, operating cost is low, bulk density is small and changes filter
The advantages of core is convenient.It has been widely used in Drinking Water purification, the filtering of industrial pure water and the filtering of other fluids.
The invention provides Water filtration structure, PP cottons used in Water filtration structure have good bactericidal property and heavy metal from
Sub- absorption property.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of particulate matter and harmful substance that can effectively get rid of in water
Water filtration structure.
To solve the above problems, the present invention is adopted the following technical scheme that：
Water inlet pipe is provided with a kind of Water filtration structure, including screen pipe, the lower end shaft core position of the screen pipe, it is described
External screw thread is provided with the outer wall position of that one end of water inlet pipe away from the screen pipe, and is connected by the external screw thread with unification
The flexible pipe of water receiving net, the flexible pipe, which has, coordinates externally threaded thread bush, and upper end cover is internally provided with the screen pipe
And bottom end cover, the bottom of the upper end cover is provided with core, PP cottons is combined between the upper end cover and the bottom end cover, described
Interference fits between PP cottons and the core, in the granulated carbon that is internally provided with of the PP cottons, the lower surface of the bottom end cover is equal
Inlet opening is furnished with, the water inlet pipe is relative with the inlet opening, the surface annular of the upper end cover is provided with multiple apopores, institute
The outside that apopore is located at the PP cottons is stated, the first dividing plate and second partition is provided with above the upper end cover, described the
The surface of one dividing plate and the second partition is evenly equipped with the first apopore, is combined between first dividing plate and the upper end cover
Medical stone, is combined with NACF, in the top of the second partition between first dividing plate and the second partition
Milipore filter is provided with, the top of the screen pipe connects an end cap, is threadedly coupled between the end cap and the screen pipe, in institute
State and depotition cock is provided with the top of end cap, the depotition cock has the valve of water management.
Preferably, the preparation method of the PP cottons comprises the following steps, and described part is parts by weight：
S1：5-10 parts of PP, 1-4 parts of diatomite, 0.005-0.05 parts of zinc oxide are poured into screw extruder and extruded, and
Cut into master batch；
S2：The masterbatch that 10-70 parts of PP and S1 steps are obtained is well mixed, and PP fibers are meltblown into using melt-blowing equipment, and
PP cottons are wound in, PP cotton products are obtained.
Preferably, the preparation method of the PP cottons comprises the following steps, and described part is parts by weight：
S1：The diatomite of 5-10 parts of PP, 1-4 parts of modifications, 0.005-0.05 parts of zinc oxide are poured into screw extruder to carry out
